AWS SDK for Python (boto3/botocore) development patterns. You MUST use this skill when writing Python code that uses AWS services via boto3 or botocore. This includes creating service clients or resources, configuring sessions and credentials, handling errors with ClientError, using paginators and waiters, S3 file transfers and presigned URLs, DynamoDB table operations, and any boto3/botocore client configuration. Use this skill whenever Python code imports boto3 or botocore, or when the user asks about AWS operations in Python.
Configures Laravel Nightwatch data collection, sampling rates, filtering rules, and redaction policies. Use when setting up Nightwatch, managing data volume, protecting sensitive data (PII), or optimizing event collection for production workloads.
Rust SDK for the iii engine. Use when building high-performance workers, registering functions, or invoking triggers in Rust.
Expert-level automotive systems, connected vehicles, fleet management, telematics, ADAS, and automotive software
Build and manage shipping integrations with Israeli carriers, including Israel Post, Cheetah, HFD, and Mahir Li, plus locker pickup services (BOX2GO, Shlager, Done). Use when user asks about "shipping Israel", "Cheetah delivery", "meshloach", "shipping label", "HFD", "locker pickup Israel", "tawit mishloach", or setting up carrier integrations for an e-commerce store. Covers carrier selection, Israeli address formatting, label generation, cross-carrier tracking system setup, and customer delivery notifications. Do NOT use for looking up a specific package tracking status (direct the user to mypost.israelpost.co.il or hfd.co.il instead). Do NOT use for international shipping outside Israel or customs/import.
Guides migration of .NET Framework Thread.Abort usage to cooperative cancellation in modern .NET. USE FOR: modernizing code that calls Thread.Abort, catching ThreadAbortException, replacing Thread.ResetAbort, replacing Thread.Interrupt for thread termination, resolving PlatformNotSupportedException or SYSLIB0006 after retargeting to .NET 6+, migrating ASP.NET Response.End or Response.Redirect(url, true) which internally call Thread.Abort. DO NOT USE FOR: code that only uses Thread.Join, Thread.Sleep, or Thread.Start without any abort, interrupt, or ThreadAbortException usage — these APIs work identically in modern .NET and need no migration. Also not for projects staying on .NET Framework, or Thread.Abort usage inside third-party libraries you do not control.
Publish Rust binaries to npm using the optionalDependencies platform package pattern. Covers the full publish pipeline, version sync, workspace:* protocol, and platform package architecture. Use when: (1) publishing Rust binaries to npm, (2) setting up the platform package pattern (main + per-OS packages), (3) debugging publish failures, (4) managing version sync across pnpm + Cargo workspaces, (5) working with workspace:* protocol. Triggers on "publish", "platform packages", "optionalDependencies", "bin.js", "version sync", "workspace protocol", "npm tag", or "prepare-publish".
Design and optimize systems for high concurrency, throughput, scalability, and elastic scale—concurrency models (threads, async/await, actors), lock-free patterns, connection pooling, caching stampede mitigation, horizontal scaling, load balancing, backpressure, queueing, rate limiting, bulkheads, read replicas, sharding, pool tuning, profiling, capacity planning, SLO-driven autoscaling, multi-region and CDN edge architecture. Use when the user asks about high concurrency, scalability, throughput, horizontal scaling, connection pooling, backpressure, rate limiting, caching stampede, read replica, sharding, autoscaling, capacity planning, lock contention, async scalability, or load balancing—not service decomposition (microservices-developer), event buses only (event-driven-architecture), generic CRUD (senior-software-engineer), SRE on-call only (site-reliability-engineer), load tests without architecture (performance-engineer), or cost-only FinOps (cloud-economist).
Create, track, retrieve, update, and delete custom business metrics for configs. Covers full lifecycle: define metric kinds via API, emit events via SDK, and query results.
Identifies domain modules, ownership boundaries, dependencies, and interfaces using Domain-Driven Design principles. Provides domain maps, bounded contexts, refactor recommendations. Use for "DDD", "domain modeling", "bounded contexts", or "service boundaries".
Implement the Syncfusion ASP.NET Core SpeechToText control for converting spoken words to text using Web Speech API. Use this skill when implementing speech recognition with Razor Tag Helpers, converting voice to text in ASP.NET Core applications, handling microphone input, processing speech events, customizing button appearance, managing listening states, or building accessible voice-enabled forms. Covers setup, speech recognition features, Razor Tag Helper syntax, events, methods, globalization, and security.
Implement responsive, resizable, and draggable panel layouts with the Syncfusion ASP.NET Core Dashboard Layout component.
